IMPROVEMENT IN HORSE-COLLAR FASTENINGS.

' Specification forming part of Letters Patent N 0- 200,339, dated February 12, 1878; application filed December 20, 1877.

To all whom it may concern: v

Be it known that 1, OHARLEs W. Ford, of the village of Sparta, in the county of Monroe and State of Wisconsin, have invented certain new and useful Improvements in Horse Collar Fastenings; and I do hereby declare that the following is a full, clear, and exact description of my invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to the class of fastenings for horse-collars opening at the bottom, which have dowel-pins and sockets and a device for locking the parts together. Heretofore they have been constructed with a springcatch, which looks the end of one of the dowelpins. They have also been made with a pin having an enlarged head, looking into a slotted plate. Neither of these devices give the necessary stiffness and strength.

My invention aims to provide a fastening which shall combine strength, stiffness, and durability, and be easily and quickly fastened or unfastened; and it consists in combining with the dowel-pins a spring-locking device,

, placed on the outside of the collar, which will be fully understood from the following description and claim.

Figure 1 is a front view of the fastening open, and Fig. 2 is a view of the socket side of the same.

The collar is first made Whole in the usual manner; then it is out through at the bottom, and the caps A fitted over the ends of the collar and securely riveted. One of the caps A has the dowel-pins b, and the other the corre' sponding sockets 0. Attached to one of the caps, and on the outside of the same, there is a flat spring, ac, projecting beyond the end of the cap, andprovided with the head n. The other cap has the staple z. The collar is fastened by inserting the dowel-pins b in the sockets 0 and pressing the caps together until the end of the spring-catch m passes-through the staple z, and the shoulder on the inside of the head n holds on the outside edge of the staple. To open the collar, the head n is pressed in until it can pass through the staple z, and then the collar is pulled apart.

The spring-catch is placed on the front of the collar, where it is easily reached, and where it serves most effectually to stiffen and strengthen the fastening.

In use the fastening has a tendency to open.

at the front. This is true of all collars which open at the bottom, and the location of the locking device on the outside and in front makes the fastening much stronger and stifl'er than is the case when it operates on the dowelpins, besides simplifying the construction of the fastening. V

I claim as my invention- The horse-collar fastening. herein described, consisting of the caps A, having the dowelpins 12 and the sockets o, in combination with the spring-catch an, attached to one of the caps A, and the lock-staple 2, attached to the other, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

CHARLES W. POTT.
